An electric power-assisted trolley mainly comprises a base, a driving unit, a threaded pull rod, a battery, a control unit, universal wheels, a handrail frame, a right handle, a left handle, a direction knob and a driving button, wherein a through hole is formed in the middle of the base, rectangular vertical rib plates are welded to the two sides of the through hole respectively in the longitudinal direction, the universal wheels are arranged on the bottom of the base, and the battery is arranged on the bottom of the base; the control unit is arranged on the base and located beside the rectangular vertical rib plate on one side, the driving unit is arranged at the position of the through hole in the middle of the base, and the handrail frame is installed behind the base; the two handles are arranged at the upper end of the handrail frame, the left handle is provided with the direction knob which can rotate within the +/-90-degree range, and the forward driving button is arranged on the right handle. By the adoption of the trolley, the problem that middle-sized C-shaped arm X-ray machine equipment is complicated in operation and hard to move transversely in the purely motor driven mode is solved, and the defects of the purely manual driving mode that efficiency is low and the requirement for physical strength is high are overcome.
